Hi Johan,

It's related to memory allocation from oracle virtual machine control manager, it's not a Database error or accident problem.
There's many reasons due to bug associated to ovm, or running x86_64 solaris on vmware. The error log BAD TRAP: type=e (#pf Page fault) rp=fffffe80004d7ac0 addr=7b5e01ff8 occurred in module "vmmemctl" shows paging not clear, as said as swapped not well, for example, at 7b5e01ff8 hexa address. Dumping the address can read more informations.
You should consider to ask to system manager.
